From: Jeff Dike <jdike@addtoit.com>

Initialize wall_to_monotonic correctly.  This fixes a problem where sleeps
lasted about one secone less than they should.  This also called for a bit of
code restructuring, following a patch which Blaisorblade had been keeping.

c7d2d28b98 [PATCH] alpha: SMP IRQ routing fix
From: Ivan Kokshaysky <ink@jurassic.park.msu.ru>

After removal of fixup_cpu_present_map() function Alpha ended up with an empty
cpu_present_map, so secondary CPUs on SMP systems are not being started.

Worse, on some platforms we route interrupts to secondary CPUs using
cpu_possible_map which is still populated properly.  As a result, these
interrupts go nowhere so the machines like DP264 aren't able to boot even with
a primary CPU.

Fixed basically by s/cpu_present_mask/cpu_present_map/.

Thanks to Ernst Herzberg for reporting the bug and testing the fix.

959eb39297 IPoIB: Fix AH leak at interface down
When ipoib_stop() is called it first calls netif_stop_queue() to stop
the kernel from passing more packets to the network driver. However,
the completion handler may call netif_wake_queue() re-enabling packet
transfer.

This might result in leaks (we see AH leaks which we think can be
attributed to this bug) as new packets get posted while the interface
is going down.

ec8510f6fe [ARM] 3540/1: ixp23xx: deal with gap in interrupt bitmasks
Patch from Lennert Buytenhek

On the ixp23xx, the microengine thread interrupt sources are numbered
56..119, but their mask/status bits are located in bit positions 64..127
in the various registers in the interrupt controller (bit positions
56..63 are unused.)

We don't deal with this, so currently, when asked to enable IRQ 64, we
will enable IRQ 56 instead.

The only interrupts >= 64 are the thread interrupt sources, and there
are no in-tree users of those yet, so this is fortunately not a big
problem, but this needs fixing anyway.

a77bc69138 [ARM] 3539/1: ixp23xx: fix __arch_ixp23xx_is_coherent() for A1 stepping
Patch from Lennert Buytenhek

The current __ixp23xx_arch_is_coherent() check assumes that the
lower byte of IXP23XX_PRODUCT_ID is identical to the lower byte of
processor_id, but this is not the case, and because of this we were
incorrectly enabling coherency on A1 stepping CPUs.

Stepping A1 of the ixp2350, which has a PRODUCT_ID of 0x401, has '02'
in the lower byte of processor_id, while A2, with a PRODUCT_ID of
0x402, has '04' in the lower byte of processor_id.

So, to check for >= A2, we really need to check the lower byte of
processor_id against >= 4.

b1ab41c494 [PATCH] slab.c: fix offslab_limit bug
mm/slab.c's offlab_limit logic is totally broken.

Firstly, "offslab_limit" is a global variable while it should either be
calculated in situ or should be passed in as a parameter.

Secondly, the more serious problem with it is that the condition for
calculating it:

               if (!(OFF_SLAB(sizes->cs_cachep))) {
                       offslab_limit = sizes->cs_size - sizeof(struct slab);
                       offslab_limit /= sizeof(kmem_bufctl_t);

is in total disconnect with the condition that makes use of it:

               /* More than offslab_limit objects will cause problems */
               if ((flags & CFLGS_OFF_SLAB) && num > offslab_limit)
                       break;

but due to offslab_limit being a global variable this breakage was
hidden.

Up until lockdep came along and perturbed the slab sizes sufficiently so
that the first off-slab cache would still see a (non-calculated) zero
value for offslab_limit and would panic with:

  kmem_cache_create: couldn't create cache size-512.

  Call Trace:
   [<ffffffff8020a5b9>] show_trace+0x96/0x1c8
   [<ffffffff8020a8f0>] dump_stack+0x13/0x15

  Kernel panic - not syncing: kmem_cache_create(): failed to create slab `size-512'

Paolo Ornati's config on x86_64 managed to trigger it.

The fix is to move the calculation to the place that makes use of it.
This also makes slab.o 54 bytes smaller.

Btw., the check itself is quite silly. Its intention is to test whether
the number of objects per slab would be higher than the number of slab
control pointers possible. In theory it could be triggered: if someone
tried to allocate 4-byte objects cache and explicitly requested with
CFLGS_OFF_SLAB. So i kept the check.

Out of historic interest i checked how old this bug was and it's
ancient, 10 years old! It is the oldest hidden and then truly triggering
bugs i ever saw being fixed in the kernel!

7f3f1d01a9 [MIPS] Fix deadlock on MP with cache aliases.
A proper fix would involve introducing the notion of shared caches but
at this stage of 2.6.17 that's going to be too intrusive and not needed
for current hardware; aside I think some discussion will be needed.

So for now on the affected SMP configurations which happen to suffer from
cache aliases we make use of the fact that a single cache will be shared
by all processors.  This solves the deadlock issue and will improve
performance by getting rid of the smp_call_function overhead.

3fa986faad [MIPS] Create consistency in "system type" selection.
The "system type" Kconfig options on MIPS are not consistent.  For
some platforms, only the name is listed while other entries are
prepended with "Support for".  Remove this as it doesn't make sense
when describing the "system type".

04b6b3b651 [MIPS] Use generic DWARF_DEBUG
When debugging a kernel compiled by gcc 4.1 with gdb 6.4, gdb could
not show filename, linenumber, etc.  It seems fixed if I used generic
DWARF_DEBUG macro.  Although gcc 3.x seems work without this change,
it would be better to use the generic macro unless there were
something MIPS specific.

6ee1da94c5 [MIPS] Update/fix futex assembly
o Implement futex_atomic_op_inuser() operation
 o Don't use the R10000-ll/sc bug workaround version for every processor.
   branch likely is deprecated and some historic ll/sc processors don't
   implement it.  In any case it's slow.

235a9d3eee [MIPS] Remove support for sysmips(2) SETNAME and MIPS_RDNVRAM operations.
SETNAME only had a minor defect but probably never had a user and
MIPS_RDNVRAM was unimplemented anyway.
